APA formatting wrong

I’m using x4 and Word 2010 and my APA output styles are not coming out right. Instead of (Author, Year) I’m getting (Author Year) without the required comma. And in my reference list, everything that should be italicized is showing up underlined!! Anybody have any ideas about what might be going on?

 It sounds like there are problems with: 1) the citation template (missing comma between the Author Year fields), and the output format (underlining instead of italicized).  

You could manually make adjustments to fix the problems but the easier and quicker fix would be to download a new style file from the EndNote website.  Just go to the toolbar, select “Help” then WEB STYLES FINDER. After downloading the APA style file, just double-click on the icon to activate/install the file into EndNote.

I am meeting the same issues with Endnote. I attemped your methods. It does not work. I download Apa 6 and copy into my Endnote and select it, but the same issues ocour to me. It seems that it is not the problem about the Apa, it is regarding the Mac system, since I operate Win 7 system on Mac and accordingly use Apa in Win system with Mac. You just afford alternative way that modify template, I checked Apa 5 template, it is diffiult to me to modify it correctly becase it is program language. Please help me figure it out. Thanks a lot.
